Specification of Letters Patent.

Patented March 13, 1906.

Application filed November 4,1905. Serial No. 235,916.

To all whom it may concern:

Be it known that I, ARGHIABALD MORRISON, a citizen of the United States, residing at Covington, in the county of Tipton and State of Tennessee, have invented a new and useful Plow, of which the following is a specification. 1

This invention relates to plows, and it has particular reference to an improved onepiece combined beam and standard of wrought iron or steel, the object of the invention being to present a device of this class which shall possess superior advantages in point of simplicity, durability, and general efficiency.

With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction of the said plow beam and standard and the novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claim,

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the pre cise structural details therein exhibited, but that changes, alterations, and modifications within the scope of the invention may be made when desired.

In the drawings, Figure 1 is a perspective detail view of the improved beam and standard. Fig; 2 is a top plan view of the same. Fig. 3 is a perspective view of a complete plow embodying the invention.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

The improved plow beam and standard is made of a single fiat bar of steel or iron which is primarily bent or doubled upon itself, as shown at 1, the doubled bar being next bent edgewise, as at 2, at a more or less acute angle. The portion of the bar terminating in the bent portion 1 constitutes the standard 3, while the ends of the bar cooperating to form the beam 4 are welded together at their extremities. The side members 5 5, constituting the standard, as well as the side members 6 6, constituting the rear portion of the beam, are suitably spaced apart. The front portion of the beam, which is composed of two thicknesses of the original bar, is drawn down or reduced about one-half, so that the front extremity of the beam will not exceed the'cross-sectional dimensions of the original bar, This is done not only with a view of saving material, but also for the purpose of reducing the weight, which in this manner may be done Without materially sacrificing its strength. Upon the front end of the beam is bolted or otherwise suitably secured a clevis 7 for the attachment of draft.

The side members 6 6 of the beam are provided near their rear ends with transverse perforations, as 8 9, and the side members of the standard are likewise provided near their upper. ends with transverse perforations, as 10 11. The perforations 8 and 10 nearest the bend or angle of the beam and standard are for the reception of bolts, rivets, or other fastening members, as 12, whereby a brace 13 is permanently secured in position for the purpose of stiffening and reinforcing the standard. The perforations 11 are for the passage of a fastening member 14, whereby the lower ends of the handles 15 are secured to the standard, said handles being reinforced by braces 15, connected with the side me1nbers of the beam by a fastening member 17, extending through the perforations 9.

A furrow-opening blade 18 is secured upon the lower end of the standard by means of a heel-bolt 19, extending between the side members 5 5 and admitting of the vertical adjustment of the blade. A sharp-edged colter 20 is provided with a shank 21, extend ing between the side members 6 of the beam and secured in position by means of a clip 22. The colter member, as will be readily seen, is capable of being freely adjusted vertically as well as longitudinally between the side members 6 6 of the beam, said side members being spaced apart for the greater portion of their lengths.

The operation and advantages of this invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. The improved beam and standard is not only simple in construction and easily manufactured at a moderate expense, but it is light, durable, and capable of resisting hard usage.

The brace member 13 may be regarded as a permanent fixture of the device; but it is obvious that various patterns of furrow-opening blades and colters may be used in connection with the device within the scope of the invention.

Having thus described the invention, what is claimed is A metallic plow beam and standard consisting of a single flat bar folded upon itself and bent edgewise to an acute angle between the doubled portion and the terminal ends, said ends being Welded together and reduced and the members in rear of the Welded portion being spaced apart, and the beam portion and the standard portion being each provided with a pair of transverse perforations, spaced apart; in combination With a brace inserted between the flat members of the beam and standard near the angle at the intersection of said beam and standard, permanent fastening means for said brace extending through the transverse perforations in the beam and standard nearest the angle, and handles and handle-braces secured upon the standard and upon the beam by means extending through the transverse perforations in said standard and beam distant from the angle.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
